The discharge of untreated waste water to the environment causes adverse environmental problems. In this regard feasible wastewater treatment system must be designed and operated to reduce the pollutant load and to safeguard the public health in that region. We are designing waste water treatment plant for approximately 4 MLD of waste water collected by various sources in Yadagirigutta region We have opted activated sludge process with extended aeration technique to treat waste water. Activated Sludge Treatment is a biological wastewater treatment process which speeds up waste decomposition by adding Activated sludge into waste water. The basic principle behind all activated sludge processes is that as microorganisms grow, they form particles that clump together. These particles (floc) are allowed to settle to the bottom of the tank, leaving a relatively clear liquid free of organic material and suspended solids. The treated wastewater is used for agricultural purposes, landscaping and street gardening. The sludge which is obtained is used as manure for the crops which yields the growth of the crops.
